Take a northwest wind flew the fine dust from the PM of the country It deteriorated the air quality, but in Baengnyeongdo Island, where the influence of foreign fine dust was well understood, the concentration of ultra-fine dust exceeded 100㎍ per cubic meter, which was'very bad'.
Today, the concentration of ultrafine dust in Seoul soared to 74 ㎍ per cubic meter, exceeding twice the environmental standard, and exceeded 40 ㎍ per cubic meter in the metropolitan area, Chungnam and Jeonbuk.
In the afternoon, yellow dust was added, which worsened the air quality.
Yellow sand, which was usually observed in spring, has been frequent in October and November from 10 years ago.
